" AUTOMATIC COVER LIFT". -r f Elmer'Lehnian, VRipon, 'Win j Applicatiannugust 4,1938', serialNe. 222,969' f This` invention appertains. to containers, and more particularly to a novel cover-raisingv and lowering device for wash maclriines,'sterilizera garbage, waste, and like containers or recep-k tacles.

One `of theprimary objects ofA my'invention isv l to provide a cover-operating mechanism embodying a foot treddle associated with the lower end of the container, and a rodconnected vwith one side of the cover, with novel means between the rod and pedal so constructed andarranged that upon initial downwardv movementxo-f the pedal, the rod will be raised, vertically until the cover is lifted clear of the container, after which the rod and cover will be rotated, so that the cover will be swung off the container.,`

' A further object of'my inventionis to rprovidev a foot-operated device for the covers` of recepfj tacles embodying a combined reciprocatory' and rotatable rod connected with one sideof the cover of the container, with means includingI a foot-pedalfor initially raising the rod and. then rotating therod.`

A still kfurther object of '.myj invention is to provide a coverfoperating mechanism of the above character, which will be durable` and'eiii-v l cient in use, one that will be' simple andv easy `to manufacture, andone which can be placed upon the market at a reasonable cost.

. With these and other objects in vvention consists in the novel construction, var-` rangement, and formation o f parts', as, will be n hereinaftermore specifically described,vclaiined,

and illustrated in the accompanyingdrawing,` in which drawing: l

`Referring lto the drawingin' detail, wherein similar reference characters sponding parts throughoutv the severalviews, the

The lower end'of the rod is vconnected to an actuating' shaft 9. The shaft 9 .can have its, upper end provided with a socket for receiving atongue or key i0 lformed on the lowery end of `the rod.l The upper end of therod is guided in litsmovement in a suitable bearing Ilv carried by the bod'yv of the.

upper end of the casing l2 has rigidly connectedk l therewith a guide sleeve I3, through which-exe tends the shaft 9. shown, the guidefsleeve. i3 is formed with'a-longitudinal slot or guideway i4, and this slotcomrnunicates at its upper end with a semicircular slot I5., which is, likewise, formedin the sleeve. `In direct axialalinement with thesleeve l3 'is a socket or bearing I6 for receiving the lowerend lof the shaft 9. The shaft extends into the sleeve and carries a -radially 'I4 and I5, as will be later set forth. s

A collar is, likeonwhicn is mtat'amymoumea l, a roller I8` for engaging the walls' of the grooves wise, carried by the shaft, andis adapted to abut the topof the casing to limit'the upward move- 1f desired, the

A light touch of thel fingers will swing the thence cover back over the container body, and downward into'contact therewith. v From the foregoing description, it can durable means for operating `the closures of garbage and like cans. y
